Nam Dinh. is a big agricultural province in Red River delta of North Vietnam, where were planted three main agricultural products: rice, corn, peanut. By case-study investigation and energy analysis, the report put out detail information on biomass energy of rice straw, rice husk, com straw, corn core, peanut straw and total biomass energy from agricultural wastes in Nam Dinh province. According to investigation data, yearly the total agricultural wastes in Nam Dinh province is more than 1l million tons. Most of this agricultural wastes in Nam Dinh province are not collected and used at current time, it is mean. | VNU Journal of Science Earth Sciences 25 2009 76-83 Potential evaluation study and application method for biomass energy from agricultural by-products rice com peanut in Namdinh Province Luu Due Hai Tran Van Quy College of Science VNU Received 24 July 2009 received in revised form 30 July 2009 Abstract. Namdinh is a big agricultural province in Red River delta of North Vietnam where were planted three main agricultural products rice com peanut. By case-study investigation and energy analysis the report put out detail information on biomass energy of rice straw rice husk com straw com core peanut straw and total biomass energy from agricultural wastes in Namdinh province. According to investigation data yearly the total agricultural wastes in Namdinh province is more than 11 million tons. Most of this agricultural wastes in Namdinh province are not collected and used at current time it is mean that Namdinh peasant dissipates a lot of biomass energy every year. In theory 1 ton of com by-products generates 477 kWh of electricity 1 ton of peanut by-products generates 450 kWh of electricity 1 ton of husk by-products generates 460 kWh of electricity 1 ton of straw by-products generates 447 kWh of electricity. In comparison with coal using husk and straw as fuels Is more economical effectively. The report aslo have proposed and chosen technological method of electricity production from husk and straw. This method is fluidized sand-bed combustion technology. Ash after being burned can be used as additive for industrial production of cement and bulding materials. Keywords . Biomass energy By-products Straw Husk Agriculture. Ỉ. Introduction Today on a global scale biomass is the fourth source energy in large average contribute is about 35 of the total energy supply . Therefore biomass energy BE hold important role in meeting energy needs of the world in the future. Using BE help to reduce the amount of waste and waste reduction of greenhouse gases help to protect the .
